in the compression chamber will v be pre vented from escaping.

One of the objects of the invention is the construction of adevice whereby the crank shafts of internal combustion engines can be securely packed in such a manner that the packing rings can be adjusted as the bearlngs and. crank shaft wear.

Another object of the invention is the construction of a packing ring especially useful for the crank shafts of internal combustion engines having a sectional outer ring provided with tongue and groove ends and a?! internal ring of webbing or other suitable material having a circumference slightly 'larger than the circumference of the two sectionsof the outer ring, when the same are closely joined together- L Withthe above and other objects 1n view the invention consists in certain novel constructions, combinations and arrangements,

of parts, clearly illustrated in the accompanying drawings, in which,

Figure I is a longitudinal sectional view of a journal box having a crank shaft provided with a packing ring according to my invention, and Fig. 2 is a detail transverse sectional view taken on line 22 of 'Fig. 1. Fig. 3 is a. sectional view of a crank pit and journal box with a crank shaft shown in pers ect'ive with my packing ring connected t erewith. v

Referring to the accompanying drawings,

1 denotes a journal box formed with an upper and a lower section detachably secured together in any suitable manner, or made in one piece as the case may be. The journal box 1s provided with an inner groove 2, and a crank shaft 3, having connection with the pistonof an internal combustion engine,.and

working in a compression chamber, extends through the journal box.

Around the crank shaft 3 a packing ring consisting of an outer and an inner ring is disposed. The outer ring is formed of two sections 4 and 5, each section composing one half of the outer ring. The section 4 is formed with end grooves 6, and the section 5 is formed with end tongues 7, which tongues are adapted to enter the grooves 6.

The inner ring consists of two similarlyshaped sections 8 and 9, which are preferably formed of a combination of webbing and graphite, thou h they may be constructed of any suita 1e material. The outer ring sections contact with the periphery of the ooves of the journal box sectlons and the inner ring sections are formed with a joint circumference slightly greater than the inner circumference of the outer ring sec? tions, so that said sections are prevented from closing against each.

As the journal bearings or crank shafts wear it is necessary to force the outer ring sections against the packing rings, and for this purpose the sections of the ournal box are provided with adjusting screws, 10 and 11, which enga e the outer ring sections on their inner entgs. The screws maybe dispensed with and s ring held pins substituted if it is desired.

It will be noticed from an examination ofthedrawin s that the packing ring 15 so located on t e journal box as to effectively prevent the gas escaping from the compression chamber, also to revent the admittance of free air instead of gas when the engine piston is on the suction stroke.

Having described my invention I claim and desire to secure by Letters Patent 1. In combination with an internal combustion enginehaving a compression chamber and a crank shaft working therein, a ournal box having an internal groove mounted on the shaft, a sectional ring having tongue and groove engaging ends disposed in the groove, and an inner ring having a greater diameter than the firstring disposed therein.

2. In combination with an internal comher and a crank shaft vvorking therein, a and adjusting screws extending into the 10 journal box for the crank shaft having an internal groove, an outer sectional ring having tongue and groove ends disposed 1n the groove, an inner ring of flexible packing material formed in SB'CtlOIlS, each sectionbeing of greater circumference than the circumference of the respective sections of the outer ring, disposed between the-outer, ring,

journal box engaging the outer ring.

In testimony whereof I afix my signature, in presence of tWo Witnesses.
